Its plenty fast for me and my handful of sites, not doing SEO for anybody. You can run up to 50 threads at a time, I think even more in version 4. Problem with it is it takes over your computer when registering or Submitting, which will be eliminated in the new version 4 coming out soon.

They are also adding a Web 2 blog module but not sure what sites it will submit too yet. A good bargain really. You have to buy some extra packets though. I got the Seo 3 package for $50 and it covers most everything as far as directories, article sites and bookmarks.

As for demon, I tried it about 1.5 years ago and I made money back. It had a lot of bugs especially connected to adding of new social bookmarking websites. But I suppose those bugs have been already fixed.

Still I use the program I mentioned and I and my clients (I provide social bookmarking service for $1.3 per 90+ bookmarks on several forums) are more than happy with the results.
